REGISTER.

- SPECIFICATION forming part of Letters Patent No. 759,748, dated May 10, 1904.

Application filed April 9, 1903. Serial No. 151,870. (No model.)

To all whom, it may concern:

Be it'known that I, GUs'rAvUs REIN, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Registers, of which the following is a full, clear, and

. exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a face view with the cover removed, a portion of the back or supporting plate being broken away and only a portion of the dial being shown. Fig.2 is a view, partly in section, looking from the left of Fig. 1, the actuating-bar being shown in its normal orretracted position. Fig. 3 is a view of the character of Fig. 2, the actuating-bar being shown in its forward or projected position. Fig. 4 is a view, partly in section, looking from the left of Fig. 1, the mechanism to the left of the resetting-bar being omitted. Fig. 5 is aview showing the totalizer and the gear which carries the pointer or indicator, said view being partly in section. Fig. 6 is a fragmentary detail view through the center of the gear-hub at right angles to the view shown in Fig. 5. Fig. 7 is a fragmentary detail view, partly in section; and Fig. 8 is a top fragmentary detail view.

My invention relates to improvements in registers, and more particularly to pool-registers, although the present mechanism can be used for other purposessuch, for example, as a fare-register.

One object of my invention is to provide an improved mechanism for actuating the device.

A further object is to provide an improved construction by means of which the indicator can be returned to its normal or zero position, and to so connect the said indicator with its recovering-spring or tension member that such spring serves in no manner to limit the operation of the indicator, and a still further object is to provide means for locking the actuating mechanism against operation during the time that the resetting mechanism is opbearing.

1 disk 13. the back or supporting plate is a longitudierative and the indicator is therefore not under the proper control of the actuating mechanism.

To these ends, and also to improve generally upon devices of the character indicated, my invention consists in the various matters hereinafter described and claimed.

Referring now more particularly to the drawings, 1 indicates the casing generally, said casing having a back or supporting plate 2 and a dial 3. Only a portion of the dial is indicated in Fig. 1, and the casing is not fully shown, such a casing as the present and its dial being well known. The dial is provided with a suitable sight-opening a and also with a suitable scale 5.

Extending from the supporting-plate under substantially the I center of the dial is a post or shaft 6, upon which is rotatably mounted a gear-wheel 7, said gear being provided with an elongated hub which produces a sleeve 8, and this sleeve preferably extends upon each side of the gear in order to provide a firm The outer end of said sleeve projects through a suitable opening in the dial and has a pointer 9 secured thereto, said pointer cooperating with the before-mentioned dial-scale 5, so that upon proper actuation of said gear 7 the pointer is moved 1 about the dial-scale.

J ou rnaled in suitable standards 10, projecting forwardly from said back plate, is a shaft 11, which is provided upon one end with a pinion 12, whose teeth mesh with the teeth of the said gear 7, said shaft extending at right angles to the before-mentioned post 6, and

upon the other end of said shaft is a ratchet- Slidable in suitable guides let upon nally-reciprocatory bar 15, whose forward end is connected to a rod or other operating member 15", which extends through the casing or is otherwise accessible to the operator, a re- ;covering-spring 15 being also suitably con- E nected to said bar. I pawls 18, whose operative ends engage oppo- Oarried by this bar are site sides of the before-mentioned ratchet 13, said pawls being yieldingly held in engagement with said ratchet by means of a spring 19, connected to the pawls. Upon reciprocation of the said bar the ratchet and its connected shaft are advanced step by step, the two pawls cooperating to carry the ratchet through a complete step. Fig. 2 shows the bar, its pawls, and the ratchet in their normal positions. Upon forward movement of the bar the rear pawl serves to advance the ratchet through one half of its complete step, as shown in Fig. 3, and upon the reverse movement of the bar the forward pawl engages a proper tooth and carries the ratchet through the remainder of the complete step, the two pawls not only serving as locking-pawls, but each serving to carry the ratchet through onehalf of a complete step.

The gear 7 is slidable longitudinally of the post 6, and its hub upon the rear side of the gear is provided with a flange 8. Independentl y rotatable upon the said hub is a sleeve or drum 38,. which is included between the rear surface of the gear and the before-mentioned flange 8, the rear end of the said sleeve being spaced from said flange in order to produce a peripheral groove or recess 23. A platespring 2 1, having one end suitably supported, is slotted at its forward end, and the arms upon the sides of said slot embrace the beforementioned hub 8 and are received in the said groove 23. Preferably an end plate 24 is connected to the free ends of the arms produced by the before-mentioned slot in the plate-spring, said end plate 248 thus becoming, in effect, a part of the spring-plate and serving to cooperate with the hereinaftermentioned bar.

Slidable in the guides 26 upon the supporting-plate is the said bar 27, said bar having longitudinal reciprocation and being substantially parallel with the before-mentioned bar 15. At a suitable point the bar 27 is cut away to leave a raised portion 28, which when the bar is in its forward normal position lies under the cooperating end of the before-mentioned end plate 24, and thus holds the platespring and the gear 7 in forward position, said gear when in this forward position meshing with the pinion 12. The tendency of this gear-controlling spring 2 1 is to move rearwardly, so that if the bar 27 be moved backwardly to carry its support 28 fronrundcr the end plate 24 said spring moves rearwardly and carries the gear 7 with it, the movement being suflicient to break the connection between said gear and the pinion 12. It will thus be manifest that with the parts in normal. position, the bar 27 being in forward position, as shown by full lines in Fig. 4, the gear 7 and the pinion 12 intermesh and movement of the actuating-bar 15 causes the desired movement of the pointer 9, as has been previously explained. hen, however, the gear 7 is moved bodily by the spring 24, as indicated by dotted lines in Fig. 4:, said gear can be freely rotated independently of the before-mentioned pinion, and the gear and pointer can thus be moved backwardly to normal or zero position without effecting movement of said pinion. Preferably a guide-pin 2 is received in a slot 2a" in the free end of said end plate 24:, the spring 24 being thus guided in its movements. 1 also prefer to extend pins 24 through the spring-plate, these pins bearing upon the end of the drum 38 and upon the before-mentioned flange 8, so that there is a point bearing between the spring and said drum and flange, and binding between said parts is prevented notwithstanding the tilting of the spring.

The bar 27 is provided with a recoveringspring 27 and can be moved baclcwardly by many means. For this purpose 1 have, however, shown a cam block or disk 31, which is rotatably mounted and cooperates with a pin 27 upon the bar 27, said cam-disk being conveniently under the control of the operator, as by means of an extending pivotal stud 31, provided with a butterfly end. The action of this cam and also of the recovering-spring 27 to effect reciprocation of the bar 27 will be clearly apparent from an inspection of Fig. i.

Reference has been previously made to the sleeve or drum 38, which is rotatably mounted upon the hub 8 of the pointer-carrying gear 7. Extending radially from said drum is a resilient arm 38, and upon the rear side of the gear 7 is a lug 7, which lies in the path of normal movement of said resilient arm. A spring 41, coiled about said drum, has one end connected thereto and its other end connected to some relatively fixed member, such as the stud 42. This spring 41 is a recovering-spring, and it tends to rotate the drum 38 and its resilient arm 38 in the direction opposite to that in which the gear 7 is driven by the actuating mechanism of the register. Upon some suitably-fixed member, such as one of the supports 10, is an inclined projection 10, which extends into the path of movement of said resilient arm 38, said arm projecting radially beyond the lug 7.

l/Vhen' the pointer 9 is at zero, the arm 38 rests against the forward side of the lug 7, and as the gear 7 is rotated the said arm 38 is correspondingly moved by the said lug 7, such forward rotation of thesaid arm serving to wind the recovering-spring 41 in a manner which will be readily apparent. If, there fore, when the pointer has advanced from its zero position the gear 7 be moved away from its cooperating gear 12 in the manner previously described, the recovering-spring, through the arm 38 and the lug 7, serves to return the gear 7 and its pointer to zero position. It is, however, desirable to permit the gear 7 and its carried pointer to be unrcstrichally rotated an unlimited number of times before being reset, and for this reason it becomes IIC necessary to provide means whereby the re covering-spring cannot simply become tightly wound, and thus lock the said gear against further forward movement. For this purpose the arm 88 is made resilient and its cooperating cam projection 10 is provided. After the gear 7 and its pointer make a complete revolution and before the recoveringspring has been so tightly wound that further forward movement of the said gear is. rendered impossible the said arm 38 engages the said cam projection, and in the further movement of the gear 7 said projection forces the resilient arm out of engagement with the said lug 7, thus permitting the spring 41 to unwind. and to rotate the drum 38 and its arm 38 until said arm again engages the forward side of the said lug. Preferably there is a space between the said cam projection 10 and the rear side of the gear .7, so that in the unwinding movement of the spring just described the resilient arm 38 can make a'complete revolution, the position of this resilient arm at the completion of such -revolution under unwinding action of the spring L1 being indicated by dot-and-dash lines in Fig. 7, the full lines in Fig. 7 showing the positions of the parts just prior to the engagement of the cam projection by the resilient arm.

A totalizer Z is provided and has its numbering-disks mounted upon the before-mentioned shaft 11, the construction and operation of the totalizer herein illustrated being old and well known, and therefore requiring no further explanation in this specification. I prefer to provide the present device with a gong 60, hammers 61 and 62, carried, respec tively, by one of the pawls 18 and by the bar 27, cooperating with said gong in a manner which will be obvious.

Although not essential, I prefer to provide means for locking the bar 15 against movement when the bar 27 is in retracted position, thus making it impossible for the mechanism to be actuated when the pointer 9 is not in proper operative connection; For this reason I have shown a locking-dog 52, pivoted between the said bars 15 and 27 and having oppositely-extending arms 53 and 54:, adapted to respectively cooperate with said respective bars, said locking-dog being normally held in what may be termed inoperative or unlocking position by means of a spring 55'. When in this position, the arm 54 (which has a cam end) lies in a recess 27 in the face of the bar 27, so that said arm lies in the path of movement of the portion of said bar forming one wall of said recess, while the arm 53 is out of the path of movement of the bar 15. When the bar 27 is moved backwardly, however, the locking-dog is rocked in a manner which will be readily apparent and is thrown to present its locking-arm 53 in the path of movement of said bar 15." When in this locking position, the arm 54 lies against the bar 27,and the locking-dog is thus prevented from moving from unlocking position until the said bar 27 returns to its forward position.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted forthose herein shown and described without in the least departing from the nature and principle of my invention.
